Water Electrolysis Calculations Physics Stack Exchange
The more complicated answer is that if you just consider the gas, and not the water that it came from, you can get more energy from burning the gas that you put in as electricity However this is misleading because you need to include the change in free energy of the water bath $\endgroup$ –Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue The iron found in iron ores are found in the form of iron oxides As a result of these impurities, iron must be first separated from the gangue and then converted to pure ironIron Production Chemistry LibreTextsManufacturing also adds to these batteries’ ecofootprint, ShaoHorn says To synthesize the materials needed for production, heat between 800 to 1,000 degrees Celsius is needed—a temperature that can only costeffectively be reached by burning fossil fuels, which again adds to CO2 emissionsHow much CO2 is emitted by manufacturing batteries?Heat rate is the heat input required to produce one unit of electricity (1 kw hr) We take a coal price of around 65 $ / Ton 3497 $ /hr; A 100 MW unit produces 100,000 units of electricity So the cost of coal per unit of electricity is (3497/100,000) 35 cents per unitHow to Calculate the Coal Quantity Used in a Power Plant

Posts mislead about environmental impact of electric cars
2022年5月8日 Social media posts shared repeatedly in Australia claim that "500,000 pounds (227 metric tonnes) of the earth's crust" is excavated to mine the materials for one electric car battery This is misleading; experts said the posts exaggerated the amount of earth that would be excavated for one battery and that the environmental impact of electric vehicles was smaller 2021年8月12日 For every ton of rare earth produced, the mining process yields 13kg of dust, 9,60012,000 cubic meters of waste gas, 75 cubic meters of wastewater, and one ton of radioactive residue This stems from the fact that rare earth element ores have metals that, when mixed with leaching pond chemicals, contaminate air, water, and soilNot So “Green” Technology: The Complicated Legacy of Rare Stoichiometry is the chemistry that mathematically relates all substances in a reaction, quantitatively relating the amount of reactants and products in a chemical reaction It allows the chemist to determine the amount of product that will form from a given amount of reactants, or the amount of one reactant that is needed to react completely with some specific amount of the Stoichiometry Chemistry Socratic2021年3月8日 Studies show that carbon footprint per ton of EAF steel can be as low as 023~046 ton CO2 depending on iron type (pig iron or scrap), electricity sources and efficiencies This would be only 10%~20% of conventional BFBOF operations [(Kirschen et al, 2011)]LowCarbon Production of Iron Steel: Technology Options,
